Answer 2

Explicação passo-a-passo:

$a) \frac{1}{2} \: \: \: \frac{1}{3} \: \: \: \: \: \: \frac{1}{4}$

m.m.c=

2, 3, 4 : 2

1, 3, 2 : 2

1, 3, 1 : 3

1, 1, 1 m.m.c =2²x3=4x3=12

$\frac{6}{12} \: \: \: \frac{4}{12} \: \: \: \frac{3}{12}$

$b) \frac{2}{5} \: \: \: \frac{2}{6} \: \: \: \frac{1}{12}$

m.m.c=

5, 6, 12 : 2

5, 3, 6 : 2

5, 3, 3 : 3

5, 1, 1 m.m.c=2²x3x5=4x3x5=60

$\frac{24 }{60} \: \: \: \frac{20}{60} \: \: \: \frac{15}{60}$

$c) \frac{4}{7} \: \: \: \frac{5}{11}$

.m.c=7x11=77

$\frac{44}{77} \: \: \: \frac{35}{77}$
